A genetic study of canine hip dysplasia

Using scores taken from pelvic radiographs of 1,186 German Shepherd Dogs, heritability estimates of canine hip dysplasia (CHD) were obtained. As measured by either of 2 scores defined, CHD was found to be 22.0% heritable. In this colony, CHD was a moderately heritable condition. To make progress in selecting against CHD, use of the progeny test to identify superior replacement breeders was stressed.
